Hi,
I was diagnosed with Type 1 diabetes at age 5. I am now 19. I haven't had any personal experience with the insulin pump, although I have heard from many doctors that the insulin pump wouldn't be ideal if you are very active. I have played sports all my life and have taken insulin injections ever since I was diagnosed. It is a personal choice, and it would probably be easier for you to decide if you did some research
Good luck!
